- 6 Claims. 1 This invention relates to improvements in cartons or containers.

The main objects of this invention'are:

First, to provide a carton or container which the invention will appear from the description, to

follow. The invention is defined in the claims.

Preferred embodiments of the invention are illustrated in the accompanying drawings, in which:

Fig. l is a front perspective view of a carton The embodiment of my invention illustrated is designed for use as a carton or container for lard andother greasy or oily products and one of the objects is to provide a suitable package for such materials without the use of greaseproof liners. To accomplish this, the structure is formed so that there are no raw edges of the I material from which the container is formed that can absorb grease or oil and cause exterior dis-,

colorations or permit the contents to seep through and become rancid as a, result of exposure.

In this embodiment, the blank shown in Fig. 11 comprises a front wall I. rear wall 2, and end walls 3 and 4, the end wall'3 being between the walls I and 2 in the blank, the end wall 4 being at one end of the blank.

or container embodying my invention completely 7 closed.

Fig. 2 is a perspective view of the carton or container with the end closures in extended or fully open position.

Fig. 3 is a fragmentary perspective view illustrating certain of the steps of closing the carton.

Fig. 4 is a fragmentary perspective view illustrating further steps in the closing of the carton and the relation of the closure members to each other.

Fig. 5 is a fragmentary perspective View illustrating the carton with the top end closures severed for providing access to the contents.

Fig. 6 is a similar fragmentary perspectiv view with the edge flap of the inner closure member adjusted to serve as a tucking flap.

Fig. 7 is an enlarged fragmentary section on line l'l of Fig. 1, illustrating the relation of the inner and outer closure members.

Fig. 8 is an enlarged fragmentary section on line 8--8 of Fig. 1 illustrating further structural details.

Fig. 9 is a fragmentary section on line 9- 9 of Fig. 1.

Fig. 9-A is a fragmentary section corresponding to that of Fig. 9 of a modified form or embodiment of the invention. 1

Fig. 10 is a fragmentary section illustrating the I the hinge connection I2.

relati'on'of the inner closure member edge flap when adjusted as a tucking flap.

Fig. 11 is a plan view of the blank from which the carton or container is formed.

At the other end of the blank, I provide a sealing flap 5 preferably of the approximate dimensions of the end wall 4, the sealing flap 5 being folded within and adhesively secured to the wall 4. This results in a tubular structure such as shown in Fig. 2. j

The rear wall 2 has an inner closure member 6 extending from the end edge thereof and joined thereto by the hinged connection 7 desirably re- 1 sulting from scoring. These inner closure members are provided with edge flaps 8 of substantial width which are joined to the outer edges of the closure members 6 by the hinge connections 9.

The end closure members Ill are joined to theend walls 3 and l by the hinge connection H and to the ends of the inner closure member 8 by These end closure members have slits l1 extending from their end edges and diagonal scores ll extending from the endsof the slits I8 to the juncture of the fold or hinge lines I l and I2.

The front wall I is provided with outer closure 'members l5 and I6 at the ends thereof, the

closure member l8 being scored at l! in spaced parallel relation to the hinge connection l8 for the outer closure member is to the front wall.

The walls and the flap 5 are joined to each other bythe hinge or score lines [9. When the carton is printed, it is preferably printed with a line 20 adjacent the upper end of the front wall and with the legend "Cut along this line.

With the parts thus arranged in relation to each other, whenthe carton is set up, the sealing flap 5 is folded within and adhesively secured to the end wall 4, with the edge 2! of the. end wall 4 in abutting relation to the adjacent wall as shown in Fig. 9. This quite effectively protects the edge 2| but should some grease or oil seep into this edge it does not reach the outer 4 upon said inner closure members, the said edge flaps of said inner closure members being folded over said end closure members, and outer closure members extending from the end edges of the front wall and folded upon said inner and end closure members and adhesively secured thereto. said end closure members being held in a collapsed folded position between said inner and inwardly and this owing to the connection of the end closure members III to the ends of the closure member 6 results in their being folded on their diagonal fold lines to the position shown in Fig. 3. The end closure members thus folded are then turned inwardly to the position shown in Fig. 4. Adhesive is applied preferably along the zones indicated at 23, Fig. 4, and the outer closure member is foldedupon the inner closure member and the end closure members. The joint flaps 8 may be folded at the same time so that it overlies the closure members it but is not adhesively secured thereto. After the contents are introduced, the closure at the othelnend is closed in the same manner.

It will be noted that with this arrangement ofparts, there are no exposed raw edges to soak up or absorb grease or oil and as a result the carton or container does not become discolored or rancid. Purchasers are loathe to purchase a package that has become discolored in any particular.

In opening the container, it is desirably out along the line and the end closure members may be economically produced and set up with machines now extensively used and closed by machines now in extensive use with slight modification thereof. a

I have illustrated and described my invention in a practical embodiment thereof. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired. Y

Having thus described my invention, what I a claim as new and desire to secure by Letters Patent, is:

1. A carton formed of an integral blank and comprising front, rear and end walls and a sealing fla overlapping one of the end walls andadhesively secured thereto, inner closure members extending from the endsof the rear wall and having out-turned flap extensions on their front edges, the flap extension at one end being adapted to constitute a tucking flap after the carton has been opened, end closure members extending from and hingedly joined to the end walls and hingedly joined to the ends of the inner closure members.

said end closure members. having longitudinal slits extending from the end edges thereof with diagonal folds extending from the inner ends of the slits to the juncture of the hinge connection outer closure members, the outer closure member at the top end of the carton being scored in spaced parallel relation to the front wall to facilitate the extending of the overlying edge flap of the inner closure member to tucking position when the front wall is out along a line adjacent to but spaced from the top end thereof and the end closure members are severed from the end walls.
